  2. 21. Retinoids in the modulation of vascular inflammation

    Author : Andreas Gidlöf; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Retinoids; metabolism; vascular smooth muscle cell; nitric oxide; inflammation; proliferation; restenosis;

    Abstract : Vascular disease is multifactorial. Smooth muscle cells, the major constituent of the normal vessel wall, play a pivotal role. The pathogenesis includes cellular differentiation, proliferation and inflammatory activation. READ MORE

  4. 22. Quantification of Arterial Wall with MRI and Image Processing

    Author : Mari Hänni; Torbjörn Andersson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; image processing; Magnetic resonance imaging; animal model; arterial wall; Radiologisk forskning; atherosclerosis; Radiological research; Radiologisk forskning; Diagnostisk radiologi; Diagnostic Radiology;

    Abstract : Quantification of atherosclerosis in vivo in animal models is of great importance when treatments against atherosclerosis are evaluated. In the studies presented in this thesis a non-invasive method combining MRI and image processing is evaluated. READ MORE

  5. 23. Retinoid metabolism and signalling in vascular smooth muscle cells

    Author : Pauline Ocaya; Allan Sirsjö; Andreas C. Gidlöf; William S. Blaner; Örebro universitet; []
    Keywords : all-trans Retinol; all-trans Retinoic acid; retinoid metabolism; proliferation; Vascular smooth muscle cells; CYP26; MEDICINE; MEDICIN; Biomedicin; Biomedicine;

    Abstract : Smooth muscle cells (SMCs) play a major role in cardiovascular diseases. In advanced atherosclerosis, blood flow is impaired due to reduced luminal diameter. Percutaneous vascular interventions, including balloon angioplasty and stent-application are commonly used for the re-establishment of luminal size and improvement of tissue perfusion. READ MORE

  6. 24. Electrophysiological effects of contrast media. Dynamic vectorcardiographic monitoring of patients during coronary angiography

    Author : Agneta Flinck; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dynamic vectorcardiography; electrophysiology; contrast media; cardioangiography; adverse events;

    Abstract : Objective: The aims of this work were to study, by means of dynamic vectorcardiography (VCG), the electrophysiological effects of contrast media (CM) injected into the coronary arteries and to evaluate which VCG variables are most suitable for comparing different CM. We also studied if CM-induced VCG changes differ from those seen after myocardial ischaemia. READ MORE

  7. 25. The role of the adventitia and perivascular tissue for the formation of intimal hyperplasia

    Author : Per Fogelstrand; Göteborgs universitet; []
    Keywords : Intimal hyperplasia; adventitia; perivascular tissue; smooth muscle cells; fibroblasts; balloon injury; vein graft; artificial graft;

    Abstract : Symptomatic atherosclerosis is commonly treated with balloon angioplasty or bypass surgery. About 30% of the interventions will re-narrow within a year due to restenosis and graft-stenosis. Thickening of the luminal layer, the intima, is an important component in these side-effects.
